SCIENCE STUDIO: Geophysics

Keith & Russ talk with geophysicist Kenneth Verosub, Distinguished Professor of Geology at the University of California at Davis.  Verosub talks about the tens-of-thousands of years it takes for the Earth’s magnetic poles to reverse, and he also discusses ways that countries might resolve water issues when a major water system is shared internationally, such as the Rio Grande along the US/Mexico Border, or the Jordan River or the Tigris/Euphrates in the Middle East.
